Man kennt Bindebandentferner z.B. aus
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Entfernen von Bindeband von mit Bindeband umreiften Gegenständen, insbesondere Coils, der eingangs beschriebenen Ausführungsform zu schaffen, welche unter Verzicht auf eine Sucheinrichtung und folglich auf Mehrkosten Wartung und schrittweisen Betrieb vollautomatisch arbeitet und auch mehrere Bindebänder im Zuge eines kontinuierlichen Arbeitsvorganges durchtrennen und entfernen kann.The invention has for its object to provide a device for removing binding tape strapped with binding objects, in particular coils, the embodiment described above, which works waiving a search facility and consequently at additional cost maintenance and gradual operation fully automatic and also several binding bands in the Through a continuous work process can cut and remove.
Zur Lösung dieser Aufgabe ist Gegenstand der Erfindung eine Vorrichtung nach Anspruch 1 zum Entfernen von Bindebänder von mit Bindebänder umreiften Gegenständen, insbesondere Coils, mit einem auf ein Coil mit Bindebandumreifung aufsetzbaren Messerkorb mit einem Messerwagen mit einem Hub- und Fahrantrieb für den über die Coilbreite und quer zu den Bindebändern verfahrbaren Messerwagen, wobei
- der Messerwagen einen Anhebekeil für die Bindebänder und ein im Bereich des Anhebekeils arbeitendes Trennwerkzeug zum Durchtrennen des jeweils angehobenen Bindebandes aufweist, und
- der Messerwagen im Zuge eines kontinuierlichen Vorschubs zumindest über die durch die Bindebandumreifung vorgegebene Coilbreite verfahrbar ist und die Bindebänder nacheinander von dem Anhebekeil angehoben und von dem Trennewerkzeug durchtrennt werden.
- the knife carriage has a Anhebekeil for the binding bands and a working in the region of the Anhebekeils cutting tool for severing the respective raised binding band, and
- the knife carriage in the course of a continuous feed at least over the predetermined by the binding tape binding coil width is movable and the binding bands are successively lifted by the Anhebekeil and severed by the separating tool.
Diese Maßnahmen der Erfindung haben zur Folge, daß ein oder mehrere Bindebänder im Zuge eines ununterbrochenen Arbeitsganges entfernt werden können, weil unter Verzicht auf eine sonst übliche Sucheinrichtung der Anhebekeil - bei dem es sich im Rahmen der Erfindung auch um eine andere Anhebevorrichtung handeln kann - kontinuierlich über die Breite des jeweiligen Coils verfahren wird, die dort befindlichen Bindebänder im Zuge seiner Vorschubbewegung anhebt und deren Durchtrennung vollautomatisch durch das Trennwerkzeug erfolgt. Dabei kann das Trennwerkzeug als ein gegen das jeweils angehobene Bindeband automatisch bewegtes, zum Beispiel ständig angetriebenes Messer oder Trennscheibe ausgebildet sein. Nach einer bevorzugten Ausführungsform der Erfindung, der selbständige Bedeutung zukommt, ist jedoch vorgesehen, daß das Trennwerkzeug als ein Rollenmesser ausgebildet ist, daß das Rollenmesser mit dem Anhebekeil einen vorgegebenen Schneidwinkel bildet und das jeweils infolge der Vorschubbewegung des Messerwagens in den Schneidwinkel einlaufende Bindeband automatisch durchtrennt. Im Rahmen der Erfindung kann es sich bei diesem Rollenmesser um ein kontinuierlich angetriebenes Messer handeln. Vorzugsweise wird jedoch ein antriebsfreies Rollenmesser eingesetzt, welches im Zuge der Vorschubbewegung des Anhebekeils und des jeweils einlaufenden Bindebandes automatisch in Rotationsbewegung versetzt wird und das betreffende Bindeband durchtrennt. Insoweit wird ein besonders einfacher und störungsfrei arbeitender Bindebandentferner verwirklicht, welche nicht nur ohne einen Suchtaster auskommt, sondern auch ohne eine Steuerung für das Trennwerkzeug und in übrigen in einem einzigen kontinuierlichen Arbeitsgang sämtliche ein Coil umreifende Bindebänder durchtrennen kann. Daraus resultiert ein weitgehend wartungsfreier und kostenminimierter Betrieb.These measures of the invention have the consequence that one or more binding bands can be removed in the course of an uninterrupted operation, because waiving a usual search device of the Anhebekeil - which may also be another lifting device in the context of the invention - continuously is moved across the width of the respective coil, which raises there binding bands in the course of its advancing movement and their separation is fully automatic by the cutting tool. In this case, the separating tool can be designed as a knife automatically moved against the respective raised binding band, for example, constantly driven knife or cutting disc. According to a preferred embodiment of the invention, which plays independent role, however, it is provided that the separating tool is formed as a roller blade, that the roller blade forms a predetermined cutting angle with the Anhebekeil and automatically cuts the respectively entering as a result of the advancing movement of the knife carriage in the cutting angle binding tape , In the context of the invention, this roller knife may be a continuously driven knife. Preferably, however, a drive-free roller blade is used, which in the course of the feed movement of the Anhebekeils and each incoming Binding tape is automatically set in rotation and the binding tape in question severed. In that regard, a particularly simple and trouble-free working binding tape remover is realized, which not only works without a search button, but can also cut without a control for the cutting tool and the rest in a single continuous operation, all a coil strapping binding bands. This results in a largely maintenance-free and cost-minimized operation.
Weitere erfindungswesentliche Merkmale sind im folgenden aufgeführt. So sieht die Erfindung vor, daß der Anhebekeil als Stufenkeil mit einer gegenüber beidseitigen Keilflächen voreilenden Keilzunge und einem Durchtrittsschlitz im Bereich der Keilmitte für das in den Durchtrittsschlitz eintauchende Trennwerkzeug und insbesondere Rollenmesser ausgebildet ist. Die Keilzunge ist besonders flach und derart angepaßt, daß die sich auf dem jeweiligen Coil befindlichen Bindebänder mit Sicherheit unterfahren und angehoben werden, und zwar in einer ersten flacheren und einer darauf folgenden zweiten steileren Stufe, so daß das mittig angeordnete Rollenmesser eine einwandfreie Durchtrennung des betreffenden Bindebandes gewährleistet. Denn das Rollenmesser ist um eine Lagerachse drehbar gelagert, die oberhalb des Anhebekeils angeordnet ist und orthogonal zur vorschubrichtung des Anhebekeils verläuft. Es wird also bei angehobenem und einlaufendem Bindeband im Zuge der Vorschubbewegung des Anhebekeils und auch des Rollenmessers automatisch in Drehbewegung und folglich Schneidbewegung versetzt. Der Messerwagen und der Anhebekeil in dem Messerwagen sind zweckmäßigerweise mittels einer Federaufhängung gelagert zumindest der Anhebekeil liegt gegen die jeweilige Coiloberfläche federelastisch an. Diese federelastische Anlage ermöglicht einen Ausgleich von Oberflächenunebenheiten im Bereich der Coiloberfläche. Ferner kann der Anhebekeil an seinem der Keilzunge abgewandten Ende zumindest eine Gleitkufe, zum Beispiel Rundkufe ausweisen, wodurch die Keilzunge ständig gegen die Coiloberfläche angestellt ist und das Unterfahren der gespannten Bindebänder sichergestellt wird. Um einen möglichst leichtgängigen Messerwagen zu verwirklichen, kann der Messerwagen Räder oder Rollen aufweisen, mit denen er auf der Coiloberfläche verfahrbar ist. Ferner ist für den Messerwagen ein eigener hydraulischer, pneumatischer oder elektromechanischer Hub- und Fahrantrieb vorgesehen. Der Hubantrieb ist erforderlich, um den in Ausgangsstellung im Messerkorb angehobenen Messerwagen mit dem Anhebekeil gegen die jeweilige Coiloberfläche abzusenken und folglich in Arbeitsposition zu überführen. Nach Beendigung der Bindebanddurchtrennung und Erreichen seiner Endlage wird der Messerwagen wieder angehoben. Der Fahrantrieb erzeugt die Fahrbewegung des Messerwagens auf der betreffenden Coiloberfläche und folglich die Vorschubbewegung des Anhebekeils sowie des Rollenmessers. Die Endpositionen der Hub- und Fahrbewegungen des Messerwagens können mittels induktiver Näherungsschalter überwacht sein.Other inventive features are listed below. Thus, the invention provides that the Anhebekeil is designed as a step wedge with a leading opposite two-sided wedge surfaces Vertex and a passage slot in the middle of the wedge for the dipping into the passage slot cutting tool and in particular roller blade. The V-tongue is particularly flat and adapted so that the present on the respective coil tie-downs are undercut and raised with certainty, in a first flatter and a subsequent second steeper step, so that the centrally arranged roller blade a perfect transection of the relevant Ensured tie ribbon. Because the roller blade is rotatably mounted about a bearing axis, which is arranged above the Anhebekeils and orthogonal to the feed direction of the Anhebekeils. It is thus automatically offset in rotational movement and consequently cutting movement in the course of the feed movement of the Anhebekeils and also the role of knife when lifted and incoming binding. The knife carriage and the Anhebekeil in the knife carriage are suitably by means of a spring suspension stored at least the Anhebekeil is resilient against the respective coil surface. This elastic system compensates for surface irregularities in the area of the coil surface. Furthermore, the Anhebekeil at its end facing away from the V-tongue at least one skid, for example Rundkufe identify, whereby the V-tongue is constantly employed against the coil surface and the underrunning of the strained tie straps is ensured. In order to realize a smoother knife carriage, the knife carriage may have wheels or rollers, with which it is movable on the coil surface. Furthermore, a separate hydraulic, pneumatic or electromechanical lifting and traction drive is provided for the knife carriage. The lifting drive is required to lower the raised in the starting position in the knife basket knife carriage with the Anhebekeil against the respective coil surface and thus to transfer into working position. After completion of the binding band separation and reaching its end position, the knife carriage is raised again. The traction drive generates the driving movement of the knife carriage on the respective coil surface and consequently the advancing movement of the Anhebekeils and the roller blade. The end positions of the lifting and driving movements of the knife carriage can be monitored by means of inductive proximity switches.
Weiter sieht die Erfindung vor, daß der Messerwagen einen sich an den Anhebekeil anschließenden unteren Klemmbalken aufweist, welcher im Zuge der Vorschubbewegung des Anhebekeils die Bandenden der durchtrennten Bindebänder auf der einen Bandseite unterfährt, und daß der Messerkorb einen oberen Klemmbalken aufweist, der bei in Endstellung befindlichen Messerwagen auf den unteren Klemmbalken niederfährt, zum Beispiel niederschwenkt und die auf dem unteren Klemmbalken aufliegenden Bandenden festklemmt. Die Bindebandklemmung erfolgt ebenfalls hydraulisch, pneumatisch oder elktromechanisch, wobei die Betriebszustände "geklemmt" bzw. "gelöst" durch induktive Näherungsschalter angezeigt werden. Der Messerkorb wird mit den durchtrennten und festgeklemmten Bindebändern zu deren Entsorgung über einen Schrottkübel verfahren. Dort werden im allgemeinen das oder die durchtrennten Bindebänder mittels eines Wicklers aufgerollt und von diesen Wickler abgestreift, so daß sie dann in den Schrottkübel fallen. - Der untere Klemmbalken weist vorzugsweise eine keilförmige Auflagefläche für die aufliegenden Bandenden der durchtrennten Bindebänder und der obere Klemmbalken mit der keilartigen Auflagefläche beidseitig zusammenwirkende Rundprofile auf, so daß eine optimale Klemmwirkung erzielt wird.Next, the invention provides that the knife carriage has a subsequent to the Anhebekeil lower clamping bar, which under the feed movement of the Anhebekeils the band ends of the severed binding bands on the one band side moves underneath, and that the knife basket a Having upper clamping bar, which moves down in the end position knife carriage on the lower clamping bar, for example, down pivots and clamps resting on the lower clamping bar band ends. The binding band clamping is also hydraulic, pneumatic or elktromechanisch, the operating conditions "clamped" or "solved" are displayed by inductive proximity switch. The knife basket is moved with the severed and clamped ties for disposal through a scrap bucket. There, in general, the one or more severed ties are rolled up by means of a winder and stripped from these winder, so that they then fall into the scrap bucket. - The lower clamping bar preferably has a wedge-shaped bearing surface for the overlying band ends of the severed binding bands and the upper clamping bar with the wedge-like bearing surface on both sides cooperating round profiles, so that an optimal clamping effect is achieved.
Weiter sieht die Erfindung vor, daß der Messerkorb auf beiden Korbseiten in Korblängsrichtung verlaufende Stützrollen oder -räder aufweist, die quer zur Korblängsrichtung schwenkbar gelagert sind. Dadurch paßt sich einerseits der Messerkorb an den jeweiligen Coilumfang an, werden andererseits die das betreffende Coil umreifenden Bindebänder nach ihrer Durchtrennung einwandfrei festgehalten bis die Klemmvorrichtung aus unterem Klemmbalken und oberen Klemmbalken die auf dem unteren Klemmbalken aufliegenden Bandenden festgeklemmt hat. Darüber hinaus wird ein einwandfreies Festhalten der Bindebänder auch für den Trennvorgang erreicht, nämlich im Zuge des Unterfahrens und Anhebens der betreffenden Bindebänder sowie deren Durchtrennung mittels des Trennwerkzeuges bzw. Rollenmessers. Die Stützrollen oder -räder können paarweise in an, Messerkorb schwenkbar gelagerten Lagerwangen angeordnet sein. Um ein Verschieben des Messerkorbs auf dem betreffenden Coil während des Anhebens und Durchtrennens der Bindebänder zu verhindern, weist der Messerkorb eine zur Vorschubrichtung von Anhebekeil und Rollenmesser entgegengesetzt wirkende und längensowie höhenverstellbare Rückhaltevorrichtung zum stirnseitigen Hintergreifen des jeweiligen Coils auf. Auch diese Rückhaltevorrichtung kann hydraulisch, pneumatisch oder elektromechanisch betätigt werden. Sie wird nach dem Trennvorgang gelöst, damit der Messerkorb angehoben und in die Schrottkübelposition gefahren werden kann. - Im Rahmen der Erfindung ist ferner vorgesehen, daß der Messerkorb eine die von den zu entfernenden Bindebandbändern gebildete Gesamtdistanz überbrückende Korblänge aufweist, und daß der Vorschubweg von Anhebekeil und Rollenmesser größer als die maximale Distanz zwischen den beiden äußeren zu entfernenden Bindebändern gewählt ist, so daß im Zuge eines Trennvorganges mit Sicherheit sämtliche das betreffende Coil umgebenden Bindebänder erfaßt und durchtrennt werden.Next, the invention provides that the knife basket has on both sides of the basket in the longitudinal direction of the basket extending support rollers or wheels, which are pivotally mounted transversely to the longitudinal direction of the basket. As a result, on the one hand fits the knife basket to the respective coil circumference, on the other hand, the binding coil strapping the coil in question properly held after their severance until the clamp from lower clamping bar and upper clamping bar clamped the resting on the lower clamping bar band ends. In addition, a perfect holding the binding bands is achieved for the separation process, namely in the course of driving under and lifting the relevant binding bands and their separation by means of the separating tool or roller blade. The support rollers or wheels can be arranged in pairs in, the knife cage pivotally mounted bearing cheeks. In order to prevent a displacement of the knife basket on the relevant coil during the raising and severing of the binding bands, the knife basket on the feed direction of Anhebekeil and roller blade opposite acting and length and height adjustable restraint on the front-side engaging behind the respective coil. This restraint device can also be actuated hydraulically, pneumatically or electromechanically. It is released after the separation process, so that the knife basket can be lifted and moved into the scrap bucket position. In the context of the invention, it is further provided that the knife basket has a basket length bridging the total distance formed by the binding tapes to be removed, and that the feed path of lifting wedge and roller knife is chosen to be greater than the maximum distance between the two outer tapes to be removed, so that in the course of a separation process with certainty all surrounding the coil concerned tapes are detected and severed.

In den Figuren ist eine Vorrichtung zum Entfernen von Bindeband von mit einem oder mehreren Bindebändern 1 umreiften Gegenständen, insbesondere Coils 2 dargestellt. Es handelt sich um einen Bindebandentferner mit einem auf ein Coil 2 mit Bindebandumreifung aufsetzbaren Messerkorb 3 mit einem Messerwagen 4 mit einem Hub- und Fahrantrieb für den über die Coilbreite und quer zu dem oder den Bindebändern 1 verfahrbaren Messerwagen 4. Der Messerwagen 4 weist einen Anhebekeil 5 für die Bindebänder 1 und ein im Bereich des Anhebekeils 5 arbeitendes Trennwerkzeug 6 zum Durchtrennen des jeweils angehobenen Bindebandes 1 auf. Der Messerwagen 4 ist im zuge eines kontinuierlichen Vorschubs zumindest über die durch die Bindebandumreifung vorgegebene Coilbreite verfahrbar, wobei die Bindebänder 1 nacheinander von dem Anhebekeil 5 angehoben und von dem Trennwerkzeug 6 durchtrennt werden. Das Trennwerkzeug ist nach dem Ausführungsbeispiel als ein Rollenmesser 6 ausgebildet. Das Rollenmesser 6 bildet mit dem Anhebekeil 5 einen vorgegebenen Schneidwinkel a und durchtrennt das jeweils infolge der Vorschubbewegung des Messerwagens 4 und folglich des Anhebekeils 5 in den Schneidwinkelbereich einlaufende Bindeband 1 automatisch. Denn das Rollenmesser 6 ist nach dem Ausführungsbeispiel nicht angetrieben, sondern wird im Zuge seiner Vorschubbewegung von dem in den Schneidwinkel a einlaufende Bindeband 1 angetrieben und funktioniert dadurch als automatisch arbeitendes Trennwerkzeug.In the figures, a device for removing binding tape strapped by one or more
Der Anhebekeil 5 ist als Stufenkeil mit einer gegenüber beidseitigen Keilflächen 7 voreilenden Keilzunge 8 und einen Durchtrittschlitz 9 im Bereich der Keilmitte für das in den Durchtrittschlitz 9 eintauchende Rollenmesser 6 ausgebildet. Das Rollenmesser 6 ist um eine horizontale Lagerachse 10 drehbar gelagert, die oberhalb des Anhebekeils 5 angeordnet ist und orthogonal zur Vorschubrichtung des Anhebekeils 5 verläuft. Der Messerwagen 4, der Anhebekeil 5 und die Räder 13 sind mittels einer Federaufhängung 11 gelagert und liegt gegen die jeweilige Coiloberfläche federelastisch an. Eine solche Federaufhängung 11 ist zugleich für den Messerwagen 4 vorgesehen. Ferner weist der Anhebekeil 5 an seinem der Keilzunge 8 abgewandten Ende zumindest eine Gleitkufe 12, zum Beispiel quer zu seiner Vorschubrichtung verlaufende Rundkufe auf, wodurch die Keilzunge 8 ständig gegen die Colloberfläche angestellt ist und im Zuge der Vorschubbewegung mit Sicherheit die zu entfernenden Bindebänder 1 unterfährt. Der Messerwagen 4 weist Räder 13 auf und ist auf der Coiloberfläche verfahrbar, er kann aber auch grundsätzlich schlittenartig in dem Messerkorb 3 geführt sein. Für den Messerwagen 4 ist nach dem Ausführungsbeispiel ein hydraulischer Hub- und Fahrantrieb vorgesehen. Dargestellt ist lediglich der Fahrantrieb 14. Die Endbewegungen der Hub- und Fahrbewegungen des Messerwagens 4 können mittels nicht dargestellten Näherungsschalter überwacht werden.The
Der Messerwagen 4 weist einen sich an den Anhebekeil 5 anschließenden unteren Klemmbalken 15 auf, welcher im Zuge der Vorschubbewegung des Anhebekeils 5 die Bandenden 16 der durchtrennten Bandbänder auf der einen Bandseite unterfährt. Der Messerkorb 4 weist einen oberen Klemmbalken 17 auf, der bei in Endstellung befindlichen Messerwagen 4 mit dem unteren Klemmbalken 15 eine Klemmvorrichtung bildet und auf dem unteren Klemmbalken 15 niederfährt, zum Beispiel niederschwenkt und dadurch die auf dem unteren Klemmbalken 15 aufliegenden Bandenden 16 festklemmt. Der untere Klemmbalken 15 weist eine keilförmige Auflagefläche 18 für die aufliegenden Bandenden 16 auf, während der obere Klemmbalken 17 mit der keilartigen Auflagefläche 18 beidseitig zusammenwirkende Rundprofile 19 besitzt.The
Der Messerkorb 3 besitzt auf beiden Korbseiten in Korblängsrichtung angeordnete Stützrollen 20, die quer zur Korblängsrichtung schwenkbar gelagert sind und nicht nur zur Positionierung des Messerkorbs 3 auf dem betreffenden Coil 2 liegen, sondern ferner zum Festhalten der Bindebänder 1 im Zuge des Anhebe- und Schneidvorganges. Die Stützrollen 20 sind paarweise in an dem Messerkorb 3 schwenkbar gelagerten Lagerwangen 21 angeordnet.The
Der Messerkorb 3 weist eine zur Vorschubrichtung von Anhebekeil 5 und Rollenmesser 6 entgegengesetzt wirkende und längen- sowie höhenverstellbare Rückhaltevorrichtung 22 zum stirnseitigen Hintergreifen des jeweilgen Coils 2 auf. Diese Rückhaltevorrichtung ist lediglich angedeutet.The
Im übrigen weist der Messerkorb 3 eine die nach dem Ausführungsbeispiel von den beiden zu entfernenden Bindebandbändern 1 gebildete Gesamtdistanz überbrückende Korblänge auf, wobei der Vorschubweg von Anhebekeil 5 und Rollenmesser 6 größer als die maximale Distanz D zwischen den beiden zu entfernenden Bindebändern 1 gewählt ist.Otherwise, the
